Abstract: A graphics processor including an interface for providing triangle primitives and line primitives representing a graphical image, a line drawer for receiving line primitives and for rendering the line primitives, and a triangle interpolator for receiving the triangle primitives from the interface and for providing line primitives therefrom to the line drawer, wherein the interface includes a register for storing graphics image line primitives and for selectively providing the stored line primitives to the line drawer.

Method for parallel fine rasterization in a raster stage of a graphics pipeline
Walter R. Steiner,Franklin C. Crow,Craig M. Wittenbrink,Roger L. Allen,Douglas A. Voorhies +4 more
- 23 Jun 2006
TL;DR: In this article, a method for parallel fine rasterization of a graphics processor is described, where a graphics primitive is rasterized at a first level to generate a plurality of tiles of pixels, and the titles are subsequently rasterised at a second level by allocating the tiles to an array of parallel second-level rasterisation units to generate covered pixels.

- 03 Feb 1999
TL;DR: In this article, a frame buffer is divided into tiles of 32 by 32 pixels, and a series of multiplexers vertically sort the vertices bases on these control bits, and then a region calculation circuit generates region bits representing a location each of the nodes with respect to the current tile.

Three-dimensional display system
Tsu Yuan Shen
- 01 Jun 1983
TL;DR: In this article, a display system for displaying a three-dimensional image on a two-dimensional raster display screen is presented, where a host processor supplies input information on the geometric elements, e.g. polygons, which make up the image to a local display processor which processes said input information and provides data concerning the location, color, intensity and depth of the points which make the surfaces of the polygon.
